Mr Barnes said earlier this year that Aldi could open more than 1,000 new stores, piling further pressure on its more established rivals.

The group said it remains on course to open 1,000 stores by 2022.

"The success of Aldi in the UK is due to the hard work and commitment of our employees, and they are crucial to our future expansion plans," the chief executive added.

The emergence of Aldi and its fellow German grocer Lidl has shaken the grocery sector's so-called Big Four - Tesco, Asda, Sainsbury's and Morrisons - who remain locked in a bitter price war sparked by the duo.

Soaring inflation linked to the Brexit-hit pound is expected to see British consumers turn to cheaper options this year, providing a further boost for the pair.
